inline assembler not permitted in thumb code

(I think that, Cortex-M3 has NVIC.)

Maybe see this:

RealView Compiler User Guide
-> Restrictions on inline assembly operations
-> Thumb instruction set

http://www.keil.com/support/man/docs/armcc/armcc_Chdgddcj.htm

If you want to include inline assembly in a source file that contains code to be compiled for Thumb, enclose the functions containing inline assembler code between #pragma arm and #pragma thumb statements. For example:

/*******************************************************************************
* Function Name : HardFaultException
* Description : This function handles Hard Fault exception.
* Input : None
* Output : None
* Return : None
*******************************************************************************/
#pragma arm
void HardFaultException(void)
{
//Big thanks to joseph.yiu for this handler. This is simply an adaptation of:

//****************************************************
//To test this application, you can use this snippet anywhere:
// //Let's crash the MCU!
// asm (" MOVS r0, #1 \n"
// " LDM r0,{r1-r2} \n"
// " BX LR; \n");
// Note that this works as-is in IAR 5.20, but could have a different syntax
// in other compilers.
//****************************************************
// hardfault_args is a pointer to your stack. you should change the adress
// assigned if your compiler places your stack anywhere else!

#pragma thumb

I've added "--apcs=/interwork" to my compiler option but I gave this error:

..\src\stm32f10x_it.c(56): error:  #1114-D: this feature not supported on target architecture/processor
..\src\stm32f10x_it.c(83): error:  #1113: Inline assembler not permitted when generating Thumb code

what else should I do?
